Toward an Abstract Relative Timeline

CHI Wokshop, Avec le Temps! Time, Tempo, and Turns in Human-Computer Interaction, 28/04/2013

Arnaud, B. Hascoët, M.

In this paper, we propose an interaction style devoted to the specification of subjective and conceptual temporal expressions. We propose an abstract relative timeline as the central support for this interaction style. Our aim is to reach a satisfactory level of expressiveness while preserving concision and clarity. We provide results from preliminary attempts to use this approach to express twenty typical target challenging conceptual temporal expressions.

Exploitation et partage de données hétérogènes et dynamiques

Thesis, 13/04/2013

Arnaud, B.

En informatique, les utilisateurs peuvent se retrouver confrontés à des actions impossibles à réaliser à cause d’options inexistantes ou devoir s’adapter à une pensée et des habitudes qui ne sont pas les leurs. Les domaines de l’informatique –bases de données, langages de programmation, …– ont chacun leur propre vision, comment gérer l’information et la présenter à l’utilisateur. Le travail préliminaire de cette thèse est une étude et une synthèse des concepts émergents qui permet de voir les équivalences d’un domaine à l’autre.

La première contribution consiste à améliorer de deux manières les favoris collaboratifs, via notre outil Coviz. (1) Chacun met en favori des documents en les marquant de ses propres vocablesé ; ces étiquettes peuvent être classées les unes par rapport aux autres selon si elles sont plus ou moins spécifiques. Le résultat, nominatif, peut être réutilisé par d’autres utilisateurs. (2) L’outil combine la recherche par mot-clé, à la manière de Google, et la sélection des caractéristiques des documents, à la manière d’eBay. Ce dernier point est commun à tous les utilisateurs, c’est-à-dire que le système considère chacune des actions individuelles comme celles d’un groupe.

La seconde contribution, majeure et confidentielle, est un outil, DIP, qui s’intègre aux logiciels existants. Son but est d’offrir plus de libertés à l’utilisateur, sur l’interaction et la présentation des informations. Le principe est de diminuer les contraintes dites « machines » du logiciel en adjoignant un nouvel accès direct entre l’utilisateur et les données disponibles. Il a été testé en condition réelle de stress avec le logiciel KeePlace. D’un point de vue final, l’utilisateur gagne en expression de filtrage –des informations– et particulièrement sur la formulation des dates, en partage, en maintien de l’état de sa navigation, en automatisation de ses tâches courantes, etc.

In information technology, end users can be faced with impossible tasks due the lack of options or need to adapt their though processes and habits to new paradigms. The domains of informatics – databases, programming languages, etc – have their own way of looking at the world and how to present information to the user. A first work of this thesis is a study and a synthesis of the emerging concepts that allow the equivalences between domains to be shown.

The first contribution consists of improving shared bookmarks in two ways though our tool Coviz. (1) Each user bookmarks documents with their own terms, these labels can be categorised against each other according to how specific they are. (2) The tool combines keyword search (like Google) with document selection by characteristic (like eBay). This last point is common to all users, that is to say all the actions of individual users are combined and considered to be those of a group.

The second major contribution (which is confidential) is a tool – DIP – that plugs into existing software tools. Its purpose is to provide greater freedom to the user over the interaction with and presentation of data. The principle is to reduce the constraints due to computer/software limitations by adding new direct access methods between the user and raw data. It was tested in the field with the tool KeePlace. The result is that the user gains in the expressiveness of sorting of data – particularly concerning dates and times –, in sharing, retaining browser state, automating day-to-day tasks, etc.

CoViz: cooperative visualization to facilitate sense making by groups of users

IV, 2011

Arnaud, B. Artignan, G. Cance, J. Delmas, G. Hascoët, M. Rodriguez, N.

Coviz is a tool that uses visualization to support spontaneous construction, organization and exploration of collections. We use the term collection to identify a set of documents gathered for a given purpose by one or several individuals. Coviz facilitates creation, organization and update of collections by providing multi-scale visualization and interaction techniques. Coviz has been tested in several informative case studies involving small groups of users. In these situations, Coviz has fulfilled several important aspects of both groups and personal organization needs. Our initial experiments indicate that Coviz can even encourage unusual and interesting forms of cooperation among people.

Marquage coopératif de documents

H²PTM, Rétrospective et Perspective 1989 - 2009, 09/2009

Arnaud, B. Hascoët, M.

Depuis quelques années les systèmes de bookmarking collaboratifs tels que blogmarks ou delicious ont rendu le marquage de documents par tag très populaire. Néanmoins les modèles de marquage existants rendent l’exploitation des tags créés encore limitée. Certains travaux ont permis d’améliorer la précision du tag notamment en hiérarchisant les tags. Dans cet article nous proposons une alternative aux modèles de marquage par tag actuels. Notre approche consiste à laisser chaque utilisateur créer sa structure personnelle de tags et de lui permettre de se coordonner partiellement ou totalement avec les autres membres. Ainsi, la création d’une hiérarchie de tags commune peut se faire de manière progressive, sans perte d’information ou dépréciation du travail individuel.

marquage de documents par tags coopération hiérarchie de tag folksonomies

Collaborative tagging systems have become increasingly popular with social bookmarking systems such as delicious or blogmarks. However, tagging models are still at their early stage. Previous work proposed hierarchies in order to enhance tag precision; however building such hierarchies cooperatively remains an open issue. In this paper, we propose an alternative to existing tagging models. Our approach consists in letting users build their individual hierarchies of tags. Shared hierarchies are further created progressively from individual ones.

Sémiotique et visualisation de l’identité numérique : une étude comparée de Facebook et Myspace

H²PTM, Rétrospective et Perspective 1989 - 2009, 09/2009

Georges, F. Seilles, A. Artignan, G. Arnaud, B. Hascoët, M. Rodriguez, N. Dresp-Langley, B. Sallantin, J.

Un modèle sémiotique de l’identité numérique construit précédemment distingue 3 ensembles de signes : (1) l’identité déclarative, (2) l’identité agissante et (2) l’identité calculée. Ce modèle est utilisé pour conduire une analyse quantitative appliquée de l’emprise culturelle du web 2.0 sur la représentation de l’identité à travers l’étude comparative de deux logiciels de réseaux sociaux, Facebook et Myspace. Contrairement au premier web, le web social rend possible l’identification personnelle d’un utilisateur sans qu’il ait à déclarer des éléments qui le décrivent ; l’analyse comparée ici présentée poursuit cette première recherche en précisant les procédés de ce nouveau paradigme identitaire et met en évidence des idéologies identitaires différentes, l’une normative par souci de socialisation, l’autre égocentrée par souci d’expression de soi. L’identité calculée incite les utilisateurs à établir des comparaisons entre eux et à nourrir leur représentation, mais il ne s’agit pas pour autant de jouer à accroître démesurément un critère comme le nombre d’amis pour jouer le jeu social attendu dans Facebook : les graphes nœud-lien montrent que le réseau s’entretient par le partage. Partager des photographies, participer à des groupes communs fait partie des échanges sociaux réguliers qui annoncent l’émergence d’un nouveau langage intersubjectif.

identité numérique visualisation Myspace Facebook networking social

Digital identity is divided into 3 sign sets: (1) declarative identity, (2) acting identity and (3) calculated identity. This typology allows leading a quantitative analysis of cultural influence of identity representation in social web, through the comparative study of two social networks: Facebook and MySpace. Unlike early web, social web makes possible identification of a user without having to declare describing elements. The comparative analysis presented here continues this analysis by specifying the procedures of this new paradigm of identity and highlighting two different ideologies of identity, on the one hand, a normative one to stimulate socialization, on the other hand, an egocentric one for the sake of self-expression. “Calculated identity” encourages users to make comparisons between them and feed their representation, but increasing disproportionately the number of friends is not sufficient to play the social game as it is structured by Facebook: visualization shows that the social network is maintained by sharing. Sharing photos, participating in shared groups is a part of regular social interaction announcing the emergence of a new intersubjective language.

Human date and hour paradigms

Problem. For the hardware and software point of view, dates and hours are stored and used in two different ways: (1) UNIX timestamps and (2) gregorian dates with (or without) babylonian hours. But human languages are filled by temporal expressions and adverbs, more appropriate for habits and manners of thinking.

Approach. Main problems are to find (i) ways for user's expressions that be more suitable for him, and (ii) ways for computer's usage that be easy to handle.

Trust peer-to-peer collaboration

Problem. Find a consensus with multiple users uses mechanisms adapted to context or targeted result, but the proceeding will depend on the good coordination and understanding between participants.

Approach. The trust peer-to-peer offers a new perspective for collaboration interactions. This paradigm focuses on the user first, on his own work for his own vision. The second time add perspective collaboration between all users in trust pairs.
